Washington, Oct 25 : Steve Jobs's new biography may be Amazon. com's top-selling book of 2011, a spokeswoman at the largest Internet retailer said on Monday.

The book titled `Steve Jobs' by Walter Isaacson, hit bookstores on Monday but was released on Apple's iBooks online store and Amazon's Kindle by late Sunday.

The late Apple co-founder's biography is the best-selling book on Amazon. com and is also listed as the top-selling electronic book on the company's Kindle eBook store.

"The way things are trending, it could very likely be our top-selling book of the year," Fox News quoted Amazon spokeswoman Brittany Turner as saying.

Although Turner did not say whether eBook versions of the biography are out-selling physical versions, James McQuivey, an analyst at Forrester Research, said that on average 50 percent of best seller books are digital and in some cases that can go as high as 70 percent.

"It's very likely for the next six months this book will outperform the physical version," McQuivey added. (ANI)
